Development Of A Gis Based Peat Swamp Forest Fire Hazard Model

Citation

Abstract / Synopsis

A GIS-Based peat swamp forest fire hazard model that integrated AHP
process and GIS analysis was developed. A GIS-grid based fire vulnerability
map was thus produced for Pekan, Pahang. High correlations (100%) were
observed between fire vulnerability zone map that derived from the model
with the hotspot distribution locations processed from NOAA satellite data in
August 2002 and actual fire spot location recorded by Pahang State Forestry
Department in 1997.
The model was tested for fire vulnerability zone using recorded actual fire
spot location and NOAA hotspot locations where all of the fire spots locations
whether from Pahang State Forestry Department or NOAA hotspots data are
located in high and very high vulnerability zone that extracted from the
model. The accuracies of maps that derived from the model were verified
using hotspot location data extracted from NOAA satellite published by
MACRES in August 2002 and actual fire spot locations published by Pahang State Forestry Department. The verification results showed an accuracy of
100%.
Arc View Dialog Designer to design Arc View Graphical User Interfaces is
used for the development of a software tool to run the model in GIS
environment. Extensive Avenue programming scripts were written to provide
additional capabilities in the development of these interfaces to meet the full
complement of operational software considering various user requirements.
The software developed not only have user friendly step by step operations
to deliver the fire vulnerability mapping but also allows authorized users to
edit, add or modify parameters whenever necessary.
